I need help with this problem: Use the five properties of exponents to simplify each of the expressions.
Power of a power: When an exponent has an exponent, both are multiplied and applied to the base of the first.
Example: (y^5)^3 = (y^15)
When multiplying terms with exponents, the exponents are added:
(y^15)(y^6) = (y^21)
When dividing, they're subtracted:
(y^21)/(y^16) = y^5
I think this is correct; Bob or the like will come along and beat me if it isn't. :P
